According to Science Daily, researchers surveyed 269 college students about various popular horror games, and surprise! The results of the study showed that almost half of respondents (44.1 percent) just can't get enough of that chill down their spine, reporting that they enjoy the feeling of being scared. Interestingly, many actually reported feeling more fear experienced through video games than through traditional media. "There a lot more of these anxious feelings … and an enjoyment of that fear," Ph.D. student and study author Teresa Lynch said, according to Science Daily.

Another finding unique to video games was that gender differences in the experience of fear were nowhere to be found. Previous studies have found that men and women experience fear similarly, but men are encouraged to shut it down, while women are encouraged to admit to it. Researchers believes that this gender difference disappears in video games because gaming tend to be a solitary pursuit.

"Our findings suggest that fearful or brave behavior during a fear-evoking experience may be a societal phenomenon," the authors wrote.

So what makes these video games so terrifying? The most frequently reported factors were "darkness, disfigured humans, zombies, and the unknown," according to the study. Furthermore, the more immersive games were seen as scarier. In contrast, natural disasters and vampires were counted among the least scary. If you're itching to feel your heart pound and your palms sweat, check out the following video games below. Some of them were specifically mentioned in the study; others are just based on personal experience. Either way, you might want to sleep with the light on tonight.

Although we'll never get Silent Hills, the Guillermo del Toro-produced addition to the Silent Hill franchise, the playable teaser is both a game in its own right and a sad reminder of what we almost had. (WE COULD HAVE HAD IT ALL, KONAMI.)
